php - AppEntityPlaylistForCompany object not found by the @ParamConverter annotation

Question

For several days now I have been stuck on this error: error : AppEntityPlaylistForCompany object not found by the @ParamConverter annotation.

Here is the code for the controller (admin_company_parcours):

controller : admin_company_parcours

If you have any ideas on what this might look like knowing that I've tried a few tricks already without success. Thanking you, cordially

Answer 1

Symfony succesfully resolves your Company entity using the id parameter in your route. However, Symfony can't automatically resolve more than one entity unless your route contains more parameters. Therefore, $playlistForCompany can't be resolved as Symfony does not know which entity to query.

As you are not persisting any new value in your code, I assume that $playlistForCompany must be an existing entity, somewhat related to $company.

1. If your Company entity has an association field to the PlaylistForCompany entity, you can retrieve it using the corresponding getter.
2. If not, you will have to use your PlaylistRepository and manually retrieve it.

public function parcours(Company $company, Request $request): Response
{
  $entityManager = $this->getDoctrine()->getManager();
  $playlistRepository = $entityManager->getRepository(PlaylistForCompany::class);

  $playlistForCompany = $company->getPlaylistForCompany();  // 1. with getter
  $playlistForCompany = $playlistRepository->find(...);     // 2. with repository

  $form = $this->createForm(PlaylistForCompanyType::class, $playlistForCompany);
  $form->handleRequest($request);
  ...
}
